I can replace *any* Property Value with a QL Expression

Data Model, Editor, Functions, Properties, QL
Summary: Huge, powerful and terrifying, but clearly correct. This would be the Querki equivalent of the common notion that, at the interface layer, a property can be either a value or a function.
Would require that all Property accesses have a context, which is not a small order. OTOH, it would make the system much cleaner and more consistent.
